CPAP Mask Comparison: Nasal vs Full Face

Nasal pillows, nasal masks and full-face masks compared

Mask category is a starting point. Cushion shape, headgear, hose connection and sizing can differ substantially within the same category, so a successful fit with one model does not guarantee the same result with another.

Nasal pillows

Nasal pillows are low-profile interfaces that direct airflow through small cushions at the nostrils. They may leave more of the face uncovered and can work well for people who read, wear glasses before sleep, sleep on their side or have facial hair crossing a larger mask seal.

Possible difficulties include nostril tenderness, dryness, headgear movement and mouth leak. Higher prescribed pressure does not automatically rule out nasal pillows; comfort and seal should be assessed with the exact model and setting rather than assumed from pressure alone.

Nasal masks and nasal cradles

Traditional nasal masks seal around the nose. Nasal cradles usually sit beneath the nostrils and avoid the bridge of the nose. These designs offer a middle ground between the very small footprint of pillows and the larger seal of a full-face mask.

They still depend on an effective nasal breathing route. Recurring mouth leak, significant congestion, dryness or pressure on the bridge needs troubleshooting. A person should not simply tighten the headgear until the leak stops, because overtightening can distort the cushion and increase skin pressure.

Full-face masks

Full-face masks—also called oronasal masks—deliver therapy through the nose and mouth. They may be considered when nasal breathing is unreliable, mouth leak continues despite appropriate troubleshooting or the prescribed care plan calls for that interface.

They are not a sign of treatment failure, but they are also not automatically the solution to every report of mouth breathing. Their larger sealing surface may require careful fitting around the nose, cheeks, mouth and lower face. Jaw movement, facial hair and contact with a pillow can change the seal during sleep.

Research comparing mask categories suggests nasal interfaces often perform well across adherence, residual events and required pressure, while individual needs still vary. This supports starting with the least complex effective interface when clinically appropriate—not refusing a full-face mask when it is genuinely needed.

Evora Full vs Vitera vs Simplus vs DreamWear Full Face

In short: the Vitera and Simplus are traditional over-the-nose masks for a stable seal; the Evora Full avoids pressure on the nose bridge; the DreamWear Full Face adds a top-of-head hose for people who move a lot, but it contains magnets. If you or your bed partner has an implant, choose one of the magnet-free full-face masks. We don’t currently sell ResMed masks.

Over-the-nose, under-the-nose and hose-position designs

Coverage category does not describe every important design difference. An under-the-nose cushion may reduce contact at the nasal bridge, while a traditional triangular cushion may feel more familiar or stable. A hose connection at the top of the head can reduce tubing across the chest; a front connection may be simpler for another user.

Consider whether the mask permits comfortable movement, whether the hose pulls when turning, whether the exhalation vent blows toward a bed partner and whether clips or adjustment points can be handled with the person’s dexterity and vision.

Silicone, fabric and memory-foam contact surfaces

Silicone is common, washable and available in many shapes. Memory-foam cushions may feel softer for some people but usually have different cleaning and replacement instructions. Fabric covers or liners may change comfort, but only compatible products should be used and they should not block exhalation vents.

Follow the exact manufacturer instructions for the cushion material. Do not apply unapproved cleaners, ozone or ultraviolet devices, essential oils, petroleum products or modifications that could damage the mask or leave harmful residue.

Mouth breathing, mouth leak and nasal symptoms

Waking with a dry mouth, seeing high leak data or being told that air escapes from the mouth may suggest mouth leak, but it does not identify the cause by itself. Nasal congestion, mask movement, humidification, pressure comfort and jaw position can all contribute.

A full-face mask may be appropriate for some people. Others may improve with a better-fitting nasal interface, management of nasal symptoms under qualified guidance, humidification review or another supported strategy. Do not tape the mouth or add a chin strap without confirming that the approach is safe and suitable. See Dry Mouth With CPAP and CPAP Mask Leaks for focused troubleshooting.

Fit the mask in the position you sleep

Fit changes when gravity, head position, facial muscles and the bed pillow change. A useful fitting process is:

The CPAP Mask Fitting guide explains this process in more detail.

• Confirm the correct mask model, cushion and headgear sizes.
• Assemble the mask according to its instructions and inspect the cushion and vent.
• Put the mask on without overtightening, then turn therapy airflow on.
• Lie in the usual sleeping positions and move the head as it moves overnight.
• Re-seat the cushion before tightening straps, making small balanced adjustments.
• Check comfort at the nose, cheeks, upper lip, jaw and back of the head.
• Review the first several nights as information gathering, noting leak location, dryness, skin pressure, awakenings and removal of the mask.

Magnetic clips and implanted-device safety

Some masks use magnets in their headgear clips. Magnets can interfere with certain implanted medical devices or metallic objects in the body, and the risk can also apply to a bed partner, caregiver or other person in close physical contact with the mask.

Check the current instructions, contraindications and warnings for the exact mask before use. If the user or someone in close contact has an implanted device or metallic object, do not assume that a general separation distance makes every mask safe. Contact the treating professional and mask supplier about an appropriate non-magnetic alternative or other next step. Health Canada has issued safety communications concerning magnets in certain sleep-therapy masks.

How to compare exact mask models

After choosing a likely category, compare the exact models using the same criteria:

• available cushion and headgear sizes, including whether a fitpack is offered;
• seal location and amount of facial contact;
• hose connection, swivel and quick-release design;
• exhalation vent location and sound;
• magnetic or non-magnetic clips and applicable warnings;
• cleaning instructions and replacement components;
• compatibility with the prescribed machine and tubing;
• Canadian availability, warranty, return terms and fitting support; and
• total ongoing cost rather than only the starter package.
